Abstract

We present measurements of the production of D^-_s mesons relative to D⁺_s mesons as functions of x_F and of p²_t for a sample of 2445 D_s decays to φπ. The D_s mesons were produced in Fermilab experiment E791 with 500 GeV/c π^- mesons incident on one platinum and four carbon foil targets. The acceptance-corrected integrated asymmetry in the x_F range -0.1 to 0.5 for D^∓_s mesons is 0.032 ± 0.022 ± 0.022, consistent with no net asymmetry. We compare the results as functions of x_F and p₂^t to predictions and to the large production asymmetry observed for D± mesons in the same experiment. These comparisons support the hypothesis that production asymmetries come from the fragmentation process and not from the charm quark production itself.
